-.Sh DESCRIPTION
-This manual page documents convenience routines for handling symbol
-tables.
-Two flavors of symbol tables are supported:
-.Bl -bullet -compact
-.It
-.Dq Regular
-symbol tables supporting insertion, deletion and lookup of entries by
-name or by value, sorting of entries, and stepping through entries in
-the table's current traversal order.
-.It
-.Dq ELF-centric
-symbol tables support additional operations for conversions to and
-from the symbol table format understood by
-.Lb libelf .
-.El
-The default traversal order for a symbol table is the order in which
-entries were inserted into it.
-This traversal order may be changed using function
-.Fn elftc_symbol_table_sort .
-.Ss Operations on Regular Symbol Tables
-Regular symbol tables use symbols that are subtypes of
-.Vt Elftc_Symbol ,
-as described in the section
-.Sx "Structure of a Symbol Table Entry"
-below.
-.Pp
-Function
-.Fn elftc_symbol_table_count
-returns the number of entries currently in the symbol table.
-.Pp
-Function
-.Fn elftc_symbol_table_create
-creates a new, empty symbol table.
-The argument
-.Ar entrysize
-specifies the size of each symbol table entry, as described
-in the section
-.Sx "Structure of a Symbol Table Entry"
-below.
-The argument
-.Ar sizehint
-specifies the expected number of symbol table entries.
-If
-.Ar sizehint
-is zero, an implementation-defined default will be used.
-.Pp
-Function
-.Fn elftc_symbol_table_create_nested
-creates a symbol table whose search scope nests inside that of a
-parent symbol table.
-The argument
-.Ar parent
-specifies the parent symbol table to nest under.
-The argument
-.Ar sizehint
-specifies the expected number of symbol table entries.
-If
-.Ar sizehint
-is zero, an implementation-defined default will be used instead.
-.Pp
-The function
-.Fn elftc_symbol_table_delete_name
-removes the symbol entry named by the argument
-.Ar name
-from the symbol table specified by argument
-.Ar table ,
-according to the rules described in section
-.Sx "Symbol Search Rules" .
-.Pp
-The function
-.Fn elftc_symbol_table_delete_entry
-removes the symbol table entry specified by argument
-.Ar entry
-from the symbol table specified by argument
-.Ar table .
-.Pp
-Function
-.Fn elftc_symbol_table_destroy
-is used to destroy a symbol table and free up its internal
-resources.
-.Pp
-The function
-.Fn elftc_symbol_table_insert
-inserts a symbol entry for the name specified by argument
-.Ar symbolname
-into the symbol table specified by argument
-.Ar table ,
-returning a pointer to a symbol table entry.
-The argument
-.Ar status
-should point to a location that will be updated with one of
-the following values:
-.Bl -tag -width indent -compact -offset indent
-.It Dv ELFTC_INSERT_ERROR
-An error occurred during insertion of the symbol.
-.It Dv ELFTC_INSERT_EXISTING
-The name in argument
-.Ar symbolname
-was already in the symbol table, and a pointer to the existing
-symbol table entry is being returned.
-.It Dv ELFTC_INSERT_NEW
-A new symbol table entry was allocated for the symbol name
-in
-.Ar symbolname .
-The application will need to initialize the application-specific
-fields of the symbol table entry.
-.El
-Insertion obeys the scoping rules described in section
-.Sx "Symbol Search Rules" .
-.Pp
-The function
-.Fn elftc_symbol_table_iterate
-iterates over the symbol table specifed by argument
-.Ar table ,
-applying the function pointed to by argument
-.Ar iterfn
-to each symbol table entry.
-The return value from the function
-.Ar iterfn
-controls progress of the iteration:
-.Bl -tag -width indent -compact -offset indent
-.It Dv ELFTC_ITERATE_ABORT
-Terminates the iteration.
-.It Dv ELFTC_ITERATE_CONTINUE
-Iteration will continue on to the next element in the symbol table.
-.El
-Argument
-.Ar cookie
-will be passed to each invocation of
-.Ar iterfn ,
-and may be used to track persistent state.
-The ordering of symbol table entries presented to function
-.Ar iterfn
-is not defined.
-The behavior of the iteration is undefined if
-.Ar iterfn
-adds or deletes symbol entries from a symbol table that currently
-being iterated through.
-.Pp
-Function
-.Fn elftc_symbol_table_lookup
-returns the symbol entry corresponding to the name of the symbol
-in argument
-.Ar symbolname .
-.Pp
-Function
-.Fn elftc_symbol_table_lookup_value
-returns the symbol entry that has a
-.Va sym_value
-field that is closest to the value specified in argument
-.Ar value .
-The argument
-.Ar table
-should point to a symbol table, that has been sorted
-by a prior call to
-.Fn elftc_symbol_table_sort .
-The argument
-.Ar searchflags
-can be a combination of the following flags:
-.Bl -tag -width indent -compact -offset indent
-.It Dv ELFTC_SEARCH_FORWARD
-Find the symbol entry with the next higher value in its
-.Va sym_value
-field.
-.It Dv ELFTC_SEARCH_BACKWARD
-Find the symbol entry with next lower value in its
-.Va sym_value
-field.
-.El
-If both
-.Dv ELFTC_SEARCH_FORWARD
-and
-.Dv ELFTC_SEARCH_BACKWARD
-are specified, then this function will return the symbol that is
-closest to the argument
-.Ar value .
-.Pp
-Function
-.Fn elftc_symbol_table_replace
-moves the symbol table entry pointed to by argument
-.Ar sym2
-into the traversal position for the entry pointed to by
-.Ar sym1 ,
-and implicitly deletes the entry pointed to by argument
-.Ar sym1 .
-Argument
-.Ar table
-should point to a valid symbol table.
-.Pp
-Function
-.Fn elftc_symbol_table_sort
-is used to define an ordering of symbol entries in a symbol
-table.
-This ordering will be associated with the symbol table till the next
-call to function
-.Fn elftc_symbol_table_insert ,
-.Fn elftc_symbol_table_delete_name
-or
-.Fn elftc_symbol_table_delete_entry .
-The argument
-.Ar cmpfn
-should point to a function that compares two symbol entries pointed
-to by
-.Ar s1
-and
-.Ar s2
-and returns -1, 0, or 1, depending whether
-.Ar s1
-is less, equal to, or greater than
-.Ar s2
-respectively.
-.Pp
-Function
-.Fn elftc_symbol_table_step
-is used to step to the next symbol in a sorted symbol table.
-Argument
-.Ar table
-should point to a symbol table.
-The argument
-.Ar cursym
-specifies the current symbol.
-The argument
-.Ar direction
-specifies the direction to step:
-.Bl -tag -width indent -compact -offset ident
-.It Dv ELFTC_STEP_NEXT
-Return the symbol which follows the argument
-.Ar cursym
-in the current traversal order.
-If argument
-.Ar cursym
-is NULL, return the first symbol in the current
-traversal order.
-.It Dv ELFTC_STEP_PREVIOUS
-Return the symbol which precedes the argument
-.Ar cursym
-in the current traversal order.
-If argument
-.Ar cursym
-is NULL, return the last symbol in the current
-traversal order.
-.El
-.Ss Operations on ELF-centric symbol tables
-ELF-centric symbol tables use symbols that are subtypes of
-.Vt Elftc_Elf_Symbol ,
-as described in the section
-.Sx "Structure of a Symbol Table Entry"
-below.
-.Pp
-In addition to the operations on regular symbol tables listed above,
-these symbol tables may be used with the following additional
-functions.
-.Pp
-The function
-.Fn elftc_elf_symbol_table_from_section
-builds a symbol table from the contents of an ELF section.
-The argument
-.Ar symscn
-should reference an ELF section of type
-.Dv SHT_SYMTAB
-or
-.Dv SHT_DYNSYM .
-The argument
-.Ar strscn
-should reference an ELF section of type
-.Dv SHT_STRTAB
-containing the string table associated wit section
-.Ar symscn .
-.Ss Structure of a Symbol Table Entry
-The symbol tables managed by
-.Lb libelftc
-are collections of symbol table entries.
-Each entry should be a subtype of one of the
-.Vt Elftc_Symbol
-or
-.Vt Elftc_Elf_Symbol
-types.
-In other words, each entry should have an
-.Vt Elftc_Symbol
-or
-.Vt Elftc_Elf_Symbol
-structure as its first member, before any application specific
-fields.
-For example:
-.Bd -literal -offset indent
-struct _MySymbol {
-	Elftc_Symbol	sym_base;
-	... other application-specific fields ...
-};
-.Ed
-.Pp
-The size of the combined entry is indicated to the library
-at the time of creating a new symbol table.
-Applications may then cast the returned pointers from these
-routines to the appropriate type:
-.Bd -literal -offset indent
-struct _MySymbol *mysym;
-
-mysym = (struct _MySymbol *) elftc_symbol_table_lookup(table,
-	    name);
-.Ed
-.Pp
-The
-.Vt Elftc_Symbol
-type has two public fields:
-.Bl -tag -width ".Va sym_value" -compact -offset indent
-.It Va sym_name
-Points to a NUL-terminated string containing the symbol's name.
-The application should not change the value of this field.
-.It Va sym_value
-The value associated with this symbol.
-This field is entirely under the application's control.
-.El
-.Pp
-The
-.Vt Elftc_Elf_Symbol
-type has two public fields:
-.Bl -tag -width ".Va sym_value" -compact -offset indent
-.It Va sym_name
-Points to a NUL-terminated string containing the symbol's name.
-The application should not change the value of this field.
-.It Va sym_elf
-A structure of type
-.Vt Gelf_Sym
-containing ELF symbol information.
-This field is entirely under the application's control.
-.El
-.Ss Symbol Search Rules
-During lookups, symbols are looked up first in the symbol table passed in
-to the
-.Fn elftc_symbol_table_lookup
-function.
-If the specified symbol is not found, and if the symbol table has a
-parent, then the search continues recursively up the chain of parent
-symbol tables till either a matching symbol is found or till there are
-no more parent symbol tables to search in.
-.Pp
-Insertions and deletion only work on the specified symbol table and
-do not recurse into parent symbol tables.
-.Ss Memory Management
-The
-.Lb libelftc
-manages its memory allocations.
-Applications should not free the pointers returned by the
-API documented in this manual page.
-.Sh RETURN VALUES
-Function
-.Fn elftc_symbol_table_count
-returns a count of the number of symbol table entries as an unsigned
-value.
-.Pp
-Functions
-.Fn elftc_symbol_table_create ,
-.Fn elftc_symbol_table_create_nested
-and
-.Fn elftc_symbol_table_from_section
-return a pointer to an opaque structure of type
-.Vt Elftc_Symbol_Table
-on success, or return NULL in case of an error.
-.Pp
-Functions
-.Fn elftc_symbol_table_delete_name ,
-.Fn elftc_symbol_table_delete_name
-.Fn elftc_symbol_table_destroy ,
-.Fn elftc_symbol_table_replace
-and
-.Fn elftc_symbol_table_sort
-return a non-zero value on success, or return zero in case of an error.
-.Pp
-Functions
-.Fn elftc_symbol_table_insert ,
-.Fn elftc_symbol_table_lookup
-and
-.Fn elftc_symbol_table_lookup_value
-return a pointer to a structure that is a subtype of
-.Vt Elftc_Symbol
-on success, or return NULL in case of an error.
-.Pp
-The function
-.Fn elftc_symbol_table_step
-return a pointer to a structure that is a subtype of
-.Vt Elftc_Symbol
-on success.
-The function returns NULL if there are no more elements in the
-specified traversal direction.
-.Pp
-The function
-.Fn elftc_symbol_table_iterate
-returns
